  • GNUstep Releases Early Wayland Support, Many Other Improvements Too

    GNUstep as the free software / GNU implementation of the Apple's Cocoa Objective-C frameworks is out with a new version.

    GNUstep's GUI library and GUI back-end are up to version 0.29 while GNUstep Base 1.28 has been released along with an updated GNUstep Makefile Package for re-implementing the APIs associated with Apple macOS.

    Notable with the GNUstep GUI Backend 0.29 is an "alpha version" of native Wayland back-end support. GNUstep software has worked with XWayland while now there is the preliminary Wayland code in place.

  • [Mesa-dev] [ANNOUNCE] mesa 21.1.0
    Hello everyone,
    
    Mesa 21.1.0 final is now available!
    There are a lot of new features, but I unfortunately didn't have time to
    make a list; I'm sure your favourite news website will pick up the slack :)
    
    The schedule from now on is to have a point release every other week,
    starting with .1 on the 19th.
    
    Cheers,
      Eric
    
  • Open source Linux GPU drivers Mesa 21.1 released

    Developer Eric Engestrom has announced the availability of Mesa 21.1, the latest release for Linux open source graphics drivers powering Intel, AMD and more.

    In the very short announcement, Engestrom mentioned Mesa will now be back to regular releases with a point release for bug fixes "every other week" which will see Mesa 21.1.1 on May 19. If you want stability, it's usually best to wait for at least that first point release.

  • Turnip Vulkan Driver Continues Maturing, Correctly Rendering More Games - Phoronix

    Turnip is the open-source Mesa Vulkan driver aligned with the Freedreno effort for Qualcomm Adreno support. Turnip has been in fairly good shape but fixes and other improvements keep flowing in as new Vulkan games/apps continue to be tested on this open-source Adreno Vulkan driver.

    Igalia developer Danylo Piliaiev has written a new blog post outlining some of the latest improvements made to this Mesa driver for allowing more Vulkan-powered software to correctly render on this unofficial Qualcomm Linux 3D driver.

Danylo Piliaiev: Turnips in the wild (Part 2)

  • Danylo Piliaiev: Turnips in the wild (Part 2)

    In Turnips in the wild (Part 1) we walked through two issues, one in TauCeti Benchmark and the other in Genshin Impact. Today, I have an update about the one I didn’t have plan to fix, and a showcase of two remaining issues I met in Genshin Impact.

    [...]

    The trees and grass are seem to be rendered incorrectly. After looking through the trace and not finding where they were actually rendered, I studied the trace on proprietary driver and found them. However, there weren’t any such draw calls on Turnip!

    The answer was simple, shaders failed to compile due to the failure in a register allocation I mentioned earlier… The general solution would be an implementation of register spilling. However in this case there is a pending merge request that implements a new register allocator, which later would help us implement register spilling. With it shaders can now be compiled!

Mesa 21.1.0 Is Released With Variable Rate Shading Support...

  • Mesa 21.1.0 Is Released With Variable Rate Shading Support For AMD GPUs, Performance Improvements And New Vulkan Extensions

    Mesa is a sniff army knife of graphics drivers and libraries that are used to provide graphics functionality on all the major GNU/Linux distributions. Mesa 21.1.0 brings Vulkan Variable Rate Shading support for AMD RX 6000 series GPUs, performance increasing graphics optimizations for the OpenGL and Vulkan drivers for both Intel and AMD GPUs, OpenGL 4.6 support in the Zink OpenGL-to-Vulkan translation layer, shader caching for the Lima driver for ARM Mali GPUs and a lot more.

    [...]

    It is almost certain that you are using the Mesa graphics library to render everything graphical if you are using a GNU/Linux distribution with everything other than a Nvidia graphics card. It provides the Vulkan and OpenGL drivers for Intel and AMD graphics cards on x86-64 hardware and a wide variety of other drivers for non-x86 hardware. The latest release is a big one that is packed with interesting features. You wouldn't know from the release-announcement which, due to time constraints, consisted of...

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
